The First Command
As an instructor . . .
Develop America's Airmen Today ... for Tomorrow
When required to use distance learning,
satellite can preserve that
classroom environment
at little or no cost!
The First Command
Still a classroom environment . . .
Develop America's Airmen Today ... for Tomorrow
Interactive Television (ITV)
– one-way video & two-way audio
– via satellite
Command
ITV emulatesThe
theFirst
classroom
at a distance
A Variety of Instructional Methods
Develop America's Airmen Today ... for Tomorrow
• You can still do:
 High-end graphics & motion video
 Live, interactive learning exercises
 Teaching interviews
 Panel discussions
 Guest speakers
 Student interaction with the experts
 Student-to-student interaction
• And like the in-residence classroom, ITV
integrates well with print & online media
The First Command
The Big Secret in DL
Develop America's Airmen Today ... for Tomorrow
Today, I’m letting you in on a
Government-wide secret:
Satellite is a cheap, fast, and
effective way to meet distance
learning requirements!
The First Command
So why the secret?
Develop America's Airmen Today ... for Tomorrow
• Satellite not frequently considered for distance
learning because it’s often considered exotic and
expensive
• Little awareness of the benefits of satellite technology
• Panacea syndrome—Web is the answer for all
distance learning
• Government schools model themselves after
academic institutions that own no global network
• Little awareness of its extensive use in corporate
America and in Federal Government
. . . so who IS using satellite?

The First Command
What’s so great about satellite?
Develop America's Airmen Today ... for Tomorrow
• Academic Effectiveness – Supports diversity of teaching
strategies & proven methodologies to enhance learning
effectiveness for all levels of learning
- Preserves & enhances the live classroom environment
- More effective environment than office area for long courses
- Low attrition, pacing assures timely completion
• Cost effectiveness – For established networks, costs are a
mere fraction of travel & per diem costs, no up-front
development costs—ROI is immediate!
• Advanced technology – Synchronous & asynchronous
medium for distribution of high-quality interactive video, CBI,
and print—bypasses Internet bottlenecks and network
firewalls—reduces latency and security issues
The First Command
What’s so great about satellite?
Develop America's Airmen Today ... for Tomorrow
• Global reach – Instant communications to virtually unlimited
number of locations world-wide
• Rapid content dissemination – Content kept current through
frequent or “on-the-fly” no-cost updating—no waiting for
outsourced updating
• Rapid deployment – Additional sites through rapid and
inexpensive downlink deployment
• Visionary approach – satellite applications consistent with
industry best practices, including blended media (or precision
learning) approaches: innovative enterprise-wide combination of
traditional & new technologies (thinking outside of the Web—
don’t put all your eggs in one basket!)

Variables used
ITV Costs:
• Operations: satellite & audio; NOC admin costs
• Maintenance: uplink, downlink, VTC (BC Links)
• Equipment: upgrades & sustainment
Residence costs:
• Only travel & per diem
Student throughput:
• Student-hour
Cost per student:
• Total costs / total student-hours
ROI
• Residence cost / ITV Cost (as a percentage)
The First Command
Cost Effectiveness - AF
Develop America's Airmen Today ... for Tomorrow
Based on AF per hour costs
One-week course: 40 Hours, 100 students
Residence TDY travel & per diem only
Total per student: $1,850
For 100: $185,000
Total per student hour: $46.25
Interactive Television:
Total per student hour: $4.43
Total per student: $177; for 100: $17,720
Cost avoidance: $1,730 per student
Total per offering (100 students): $173,000
Costs for ITV are 9.6% of residence!
ROI: 1,044%
The First Command
School Cost Effectiveness
Develop America's Airmen Today ... for Tomorrow
Based on actual per hour costs
(Satellite costs centrally funded by AETC)
Interactive Television:
Audio costs (10 sites, 10 students per site): $400
BC Costs (not at AFIT): $360
Total per student: $7.60
For 100: $760
Total per student hour: $0.19
Cost avoidance: $1,842 per student
Total per offering (100 students): $1,842,400
Costs for ITV are 0.41% of residence!
ROI: 24,342%
The First Command
What is the ATN Advantage?
Develop America's Airmen Today ... for Tomorrow
• Academic Effectiveness – AF Schools have experienced a 1to-2% increase in performance compared to resident–
attrition no more than 9% (long courses)
• Mission Effectiveness – ATN is mission-centric—optimizes
pacing—controls length of instruction and time of
completion.
• Advanced technology – Migrating to DVB-S2 & IP
broadcasting to reach classrooms more cost effectively, and
reach desktops when applications require it, and provide for
large-file transfer to remote servers
• Global reach – Meeting DL requirements through single,
standardized, enterprise-wide network (2+ sites per AF
base)—a force multiplier—and coverage is expanding
• Cost effectiveness – Very lean operations—Represents only
0.4% - 9% of travel & per diem costs, no up-front development
costs—ROI is immediate!
The First Command
What is the ATN Advantage?
Develop America's Airmen Today ... for Tomorrow
• Rapid content dissemination – Content kept current through
immediate & frequent updating by instructor—not outsourced
• Rapid Deployment – Additional sites through rapid and
inexpensive downlink deployment (~$11K CONUS, ~30K
OCONUS)
• Continuing Growth in Joint Applications – More agencies are
turning to ATN and GETN to meet DL needs—the only
interagency DL network
• Visionary approach – Broadening satellite applications and
forming alliances across AF, DOD, & Federal Government to
share instruction and other programming, and to reduce costs
by collective purchase of technology and bandwidth
• Supports AF aims:
-- CSAF White Paper, “Nations Guardians”
-- CSAF “USAF Transformational Initiatives”
-- AETC White Paper, “On Learning,” 30 Jan 08

Where Are We Going?
Develop America's Airmen Today ... for Tomorrow
• Air Force Channel
- Akin to Pentagon Channel, but more targeted (working
w/ NMUSAF, AF/PA, AETC History Office, DMA)
- Dedicated channel for historical & current content
AU History Channel
NMUSAF & AFIT Guest Speaker Programs
Public Affairs Office programs
AF & MAJCOM info distribution
CC calls
Town hall meetings
Emergency/deployed com
DMA applications
. . . and more
The First Command
Where Are We Going?
Develop America's Airmen Today ... for Tomorrow
• ATN Next Generation—Video-to-the-Desktop & Data
broadcasting to networked environment
- For short –duration applications (e.g. 1 hr) not requiring
classroom environment
- For store-and-forward applications
- Linking ATN to LAN head-ends for video distribution to the
desktop (noninteractive)—no need for CoN
- Maxwell AFB’s current system
- AMC current configuration is “ATN ready”
- Ultimately linking directly to the desktop—applying for CoN

Develop America's Airmen Today ... for Tomorrow
• Satellite broadcasting efficient for multipoint largefile transfer—high-speed data delivery
• Bypasses heavily burdened Internet infrastructure
• Eliminates firewall barriers
• Delivers media-rich ADL instruction, full-screen/
full-motion video to classroom, desktop, or laptop

• Seamlessly integrates w/LMS for SCORM-based
courseware
• Reaches unwired deployed warriors and avoids
C2 networks
• Adheres to current best practices in industry
The First Command
The Future of ATN
Develop America's Airmen Today ... for Tomorrow
• ATN will continue to expand as interagency sharing of
programming increases—especially for rapid
dissemination of health, disaster relief, national security
information, & required warrior training
• As ATN connects to local servers, IP content (video or
courseware) will be streamed or stored for asynchronous
applications—especially for OCONUS
• One network, ATN, will allow instructors or commanders in
front of a camera in a studio, lecture hall, auditorium, VTC
unit, or mobile camera, to reach their audience at their
desktops or in front of any TV connected to their local
base cable network—all at once or to selected sites only
